IB SSL box

I noticed the IB sign in screen has a box for SSL. I assume that is secure sockets layer. I thought all these broker platforms used that routinely, guess not. Should this be checked? Any reason not to use it?

I'm not an expert on this but I've read others say around 30 milliseconds. This number is just a recollection so if someone else knows please chime in.
